This hasbro sparking launcher is pretty awesome and worth the time and money , better than a string launcher were you have to buy 2 different ones for left and right beys this one comes with both ways to launch I recommend it to everyone!
The Beyblade has 1 of those bumpy bottoms but extra long? When I tried without sparks it spun well! With sparks it could barely spin, since they should have decreased instead of increased. That way it would have spun more stable at a faster speed!
